spikelet number, leaf size, root system, and the number of vascular bundles, indicating the
enhancement of source size and translocation capacity as well as sink size.
The basic premise of high yield in rice is to improve leaf photosynthetic efficiency and coordinate
the source sink relationship in rice plants. Quantitative trait loci (QTLs) related to morphological
traits and chlorophyll content ofrice leaves were detected at the stages of heading to maturity,
and a major QTL (qLSCHL4) related to flag leaf shape andchlorophyll content was detected at
both stages in recombinant inbred lines constructed using the indicarice cultivar93-11 and the
japonica rice cultivar Nipponbare. Map-based cloning and expression analysis showed that
LSCHL4 is allelicto NAL1, a gene previously reported in narrow leaf mutant of rice(Zhang et al.,
2014).
